Toichiro Suzuki originated from Seasoning City, retaining scant childhood memories and displaying no reluctance to devastate his hometown during his schemes. Discovering his psychic gifts in middle school cemented his conviction of inherent superiority, propelling him through a life devoid of failure or remorse until founding Claw to pursue global conquest. This ambition fractured his family, prompting his wife to depart with their son, Sho Suzuki. Two decades prior to the main events, Suzuki initiated the accumulation of vast psychic energy reserves to fuel his goals. He established Claw, recruiting potent espers by granting them mastery over unstable abilities—exemplified by providing Serizawa an umbrella to contain his powers. Espers who challenged Suzuki but proved inadequate received facial scars and assignment to the Scar unit, while formidable opponents earned positions among the elite Ultimate 5. His core philosophy asserted esper supremacy over non-psychic humans, whom he deemed inferior. Suzuki consistently projected arrogance, egotism, and emotional detachment, self-proclaiming as Earth's absolute ruler after encountering no stronger esper in his worldwide travels. He typically maintained a neutral expression but revealed intense exhilaration in combat, especially against Shigeo Kageyama. He showed no regard for lives, even attacking his own son Sho without hesitation when confronted. Yet he wielded manipulative charisma, feigning empathy to secure followers like Serizawa. His sole acknowledged emotional tie was to his estranged wife, whom he intended to reunite with after achieving world domination. His abilities encompassed storing and transferring vast psychic energy, enabling him to lend power to subordinates or reclaim it instantly. He could induce sleep, generate ethereal clones, manipulate elements like fire and ice, and exert immense telekinetic force. Increasing his Power Output percentage during combat induced physical transformations: bulging veins, energy surging from his eyes and mouth, and expanding musculature. At 100% output, his body ignited in flames, though this state risked self-destruction from energy overload. The confrontation with Shigeo Kageyama proved pivotal. After dominating their initial clash and reaching 100% power, Suzuki's form destabilized. Shigeo intervened, compassionately absorbing the lethal excess energy—an act that profoundly impacted Suzuki, leading to his voluntary surrender. Before imprisonment, Suzuki expressed genuine concern for Serizawa's susceptibility to manipulation and apologized to Sho for the familial rupture caused by his arrogance. He reflected on Shigeo's attempt to shake hands during their battle, reaching out himself in a symbolic gesture acknowledging the need for human connection. Later, during an emergency involving Shigeo's uncontrollable psychic rampage, the government released Suzuki for assistance. He acted independently but was quickly overwhelmed, underscoring his reduced stature and continued survival. Subsequent appearances, like the Spirits and Such Company trip to Ibogami Hot Springs, featured minimal involvement from Suzuki, who remained under government oversight. Physical recovery from his climactic battle was evident in his slightly fuller cheeks compared to his immediate post-destruction state.
